About this item

This rugged, waterproof portable meter is designed for a wide range of pH, mV, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity and temperature testing and field applications. It can be used in the most demanding locations thanks to its IP67-rated housing. The meter offers two measuring channels allowing users to measure pH and conductivity simultaneously or view each channel separately.

Up to a five point pH calibration using automatic buffer recognition of NIST or DIN buffer groups with choice to manually enter custom buffer values
Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation
Easily view individual measurements on a full screen display and quickly toggle to a split screen display to view multiple measurements simultaneously
Measurement stability indicator and selectable read modes – Auto-Read holds a stable reading, Continuous shows changing readings with hold option and Timed logs data at specific intervals
Data log collects and date/time stamps up to 5000 measurement sets with optional sample ID and user ID
Calibration log stores ten most recent calibrations
Orion Star Com software facilitates data transfer to a computer via USB or RS232 connections

Measure pH, mV, relative mV or ORP with temperature on channel one and measure conductivity, TDS, salinity or resistivity with temperature on channel two.

Auto-ranging conductivity values offer consistent readings across entire measurement range without need to recalibrate. Use linear, non linear, EP (USP) or off conductivity temperature compensation with 5, 10, 15, 20 or 25 °C reference temperatures.

Delivery: Supplied with four with 4 AA batteries, literature CD, printed quick start guide, computer interface cable and meter test certificate.
The kit additionally includes: 8107UWMMD ROSS Ultra Triode gel-filled epoxy-body pH/ATC electrode (3 m cable), 013010MD DuraProbe 4-cell (K=0,475) epoxy-body conductivity sensor (3 m cable), Orion pH 4/7/10 buffer pouches (10 packs each), ROSS electrode storage solution (475 ml), Orion rinse solution pouches (10 packs), Orion 1413 µS conductivity standard pouches (10 packs), Orion Star A series portable meter armor and Orion Star A series hard-sided field case.
